Abstract

The article gives geological characteristic of ore and enclosing rocks at Sekisovskoe gold deposit. The underground mining involves room-and-pillar and sublevel caving for medium thick ore bodies and shrinkage stoping for thin ore bodies. The use of the solidifying backfill technology is validated. Based on the laboratory research into rheological and strength properties of backfill mixtures, rational backfill compositions are proposed for the said deposit. The technical and economic estimation of backfilling scenarios in Sekisovsky Mine is made for: 1) preparation of backfill in a mixer-activator and gravity flow in pipeline; 2) backfill preparation in a concrete mixer and feed in mine via vertical holes and horizontal mine mixers. Efficient flowsheet is developed for backfill feed from the surface backfill plants. Selection of the rational backfill technology for Sekisovskoe deposit is described.
